Be careful too, I am not sure about that exact clausing, but many machines have adjustable headstocks too. Nardini, Some Clausings, Many Others.
I bought a machine about 5 years ago, it was a clausing from the 1970's. Got it for $100, because the guy bought it and was so fed up with the wear on it, he bought it on Ebay, it was shipped to him, and said he got ripped off on the condition. Well I had a machine that needed parts, so perfect match. Supposedly this guy was an expert machinist for 20 years.
I went to check this out, for $100 I was not gonna even look at it, was just gonna take it. I told him on the phone it was sold, never saw a picture or anything, just was a listing with phone number.
He said it was cutting a .010 taper in only about 3". I expected to see a mess. But it had the parts on it I needed, (thread dial and a few handles)
I got there and glanced at it, like I said for $100 I was taking it, and expecting to see a worn machine with a few parts I needed. I looked at it and thought the paint looked pretty darn good for a machine with so much wear. Then went to look closer, looked at the bed, and thought to myself, damn these ways look NICE. Oh well, still thought nothing of it. We picked it up with his lift, put it on my trailer and away I went.
Got back to the shop and started playing around with it, and looked closer and saw it was not worn at all. Looked at the headstock, noticed it looked like many of the new machines we carry, ADJUSTABLE.
Spent an hour getting it all set in, and had it turning within about .0005" over 6".
I called him to explain, told him what I did, he said it still was a POS and has to be worn, etc. I offered it back to him because I felt bad, and he did not want it. (I didnt say I got it within .0005, I just said much better than it was)
He was a pretty rude person too afterwards, a crab ass really. So I did not feel bad at all, especially since I called and told him and he said I didnt know what the hell I was talking about, maybe I need to learn to read a mic. Good for him, maybe he should learn to look into things instead of jumping to a conclusion and being hard headed.
Moral of the story, look closely, if its cutting a lot of taper, it may not be bed wear.
